Can you provide errors from var/log/exception.log file? It looks like error in logic and not in graphql-schema.

It looks like you have modified the graphql schema after your first query. The change that you have made will probably be change Int to String in the schema.

Perhaps you can solve it by running setup:upgrade.

I would recommend to use https://github.com/mage2tv/magento-cache-clean which will automatically flush the stitched schema when you make modifications to a schema file.
